TH0190 Handheld Precision Voltmeter

Product Description

1. SummaryTH0190 is a handheld precision AC current pressure gauge that can accurately measure the range of 20 mV ~ 10 V small-signal voltages, and the AC voltage measurement capability is better than 8-digit semi-high-precision standard digital multimeter. 2. Features Frequency range: DC, 40 Hz ~ 10 kHz. DC measurement uncertainty up to 30 ppm. Cross-current measurement uncertainty up to 50 ppm@53 Hz. 2nd~64th harmonic measurement, DC ripple measurement function. LCD color screen, digital button operation. 3. Applications Accurate measurement of AC and DC voltage and current on site. Calibrate AC and DC voltage standard sources/meters, current standard sources/meters.

☆ Measure the AC/DC voltage

It can be used with precision voltage divider (such as TH0150 / TH0170) formation of AC/DC voltage measurement system. It can be used to measure the AC/DC voltage, AC/DC voltage source.

☆ Measure AC-DC current

It can be used with I/V conversion standards (such as TH0400 / TH0500U) to form an AC/DC current measurement system. It can be used for measuring AC/DC current signal, the calibration of AC/DC current source.

4. Characteristics

☆ Measure ripple or distortion

The instrument supports DC, AC measurement mode, AC frequency range: 40 Hz ~ 10 kHz. When measuring voltage, distortion and ripple measurements can be completed simultaneously, the maximum measurement bandwidth of DC ripple is up to 1 kHz, and AC supports the measurement of the 2nd ~ 64th harmonic.
